Wheels Manufacturing Inc.
PressFit 30 Bottom Bracket Sealed Bearings

Details

Wheels Manufacturing's PressFit 30 Bottom Brackets are an excellent direct replacement for SRAM, FSA and other PressFit 30 BBs. They are 100% made in the USA with machined aluminum cups for superior durability and your choice of standard sealed, angular contact or ceramic bearings (this model has sealed bearings). Wheels Manufacturing also exclusively uses Enduro bearings for excellent performance and longevity. Other great features of these stellar BBs include a 12% increase in bearing strength over standard models; serviceable bearings; dual exterior silicone rings for easy installation and to eliminate creaking; double-lip bearing seals; and even the highest quality grease appropriate for bottom bracket use and also more of it for smoother running and maximum durability!

You get radial deep-groove bearings that have 5/32-inch Grade 20 balls, the largest in the industry, resulting in a 12% increase in static load compared to standard 6806 bearings. Dirt and outside elements are kept out by no less than two double-lip seal systems. The bearing seals are dual-lip, groove-type seals rather than standard 2RS types that other manufacturers use; one lip to keep the dirt out and the other to keep the 90% grease fill inside.

Also, the bearings are filled on both sides with Mobil HP 222 synthetic grease for the best protection and long-lasting setup. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration, too!

Enduro Angular Contact (A/C) cartridge bearings are specifically designed for bottom brackets (and hubs). In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear.

Grade 5 Chromium Steel Balls: High precision balls are within 5/1,000,000? round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade.

Because of the internal ball path design, all of the balls are engaged 100% of the time lending even and maximum support through the entire pedal stroke. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction.

"LLB" dual-lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.

Wheels Manufacturing backs them up with a 1 year warranty.

3) Enduro Ceramic Hybrid Sealed Bearings - Fastest

Enduro Ceramic Hybrid bearings have Grade 5 ceramic balls with ABEC 5 chromium steel races. Bearings are made from pure Silicon Nitride material with extreme high density from uniform compaction, the micro-structural development of this material during manufacturing is second to none.
